I have P320 Sangoma Phone and I have issue after booting up.
The phone don’t response and keep
giving same error message “Error contacting proxy server. You can retry, choose a new server, or reset any stored credentials and then retry.”
I tried to Update & downgrade the firmware but still same.
Do other P320s on your network work just fine? Have you verified that the phone is connected to the correct network and receiving a correct/expected IP address?
Hmm, try assigning the phone’s mac address to an extension in the PBX GUI first and see if that will work. If you are using DMPA to provision the phones you can check/watch the asterisk logs /var/log/asterisk/full for the phone attempting to provision.
I think I have a similar situation, working on some P315 phones, they are new but claimed, they were pointed to a different deployment.
I’m using a Cloud hosted FreePBX, using DMPA for provisioning with VPN enabled.
In the Sangoma portal the devices are not following the “no redirect” setup.
The devices will give me connecting error if they have no IP/FQDN.
If I enter IP/FQDN (with redirect set to “no”) the phone will reach server will connect to the VPN, try to download config files but will reboot and will stay on a loop.
The IP/FQDN address looks off. Make sure the deployment is set up correctly in the portal, phones tab, for the D/P Phones. Then set the phone to do Deployment type redirect and select your dep ID.
